Jacketed gear pump(internal or external rotary gear pump) mainly used to transfer asphalt, paraffin, resin.Pump with whole heating jacket,Applicable temperature less than 350℃.
Jacketed gear pump housing is provided with hollow interlayer. The transfer liquid and pump are heated and insulated by steam, hot water, heat conduction oil, etc.If the liquid viscosity is high, it is recommended to use reducer, speed regulating motor or pulley transmission.Slow down the pump.This pump is suitable for conveying liquids which are easy to solidify or crystallize at room temperature.Such as bitumen, paraffin, rosin, soap liquid.Before starting the pump, it should be preheated to reduce the starting power of the pump.Maximum applicable temperature 350℃,
It is suitable for the liquid with solidification or crystallization at room temperature, which is easy to flow and lubricate by heating and maintaining a certain temperature, as well as the outdoor installation and process in the cold area where insulation is needed. When the pump starts to work, the first preheating reduces the starting power of the pump.
It is suitable for conveying corrosive or non-corrosive liquid with high requirements of sanitary conditions. The conveying medium does not contain solid particles, the temperature is not higher than 350℃, and the viscosity is 5cst-1500cst liquid, such as various chemical raw materials, filling medicine, food, cosmetics, detergent, printing and dyeing, brewing, resin, rubber and other industries.
The pump drive mode has motor direct connection and reducer two, when the liquid viscosity more than 1500cSt, should use reducer drive.
Jacketed Gear Pump External Type
The pump body is provided with a hollow interlayer and an inlet and outlet flange, which can be used for heat conduction oil, steam, hot water, and other media to heat the transported liquid and pump for heat preservation and cooling. The pump is driven by motor direct connection and reducer. When the liquid viscosity exceeds 1500cSt, the reducer shall be used to drive.
This type of pump has strong self-priming performance . Suitable for conveying viscous liquids without solid particles and fibers, even semi-solid liquids, with high delivery viscosity up to 300000 cst.So , this is a excellent high viscosity gear pump.
It has the advantages of small size, light weight, small pulsation, low noise, smooth operation and long life.
The pump can be widely used in oil, pigment, pigment, food, soap, detergent and other industries.
Jacketed Gear Pump Internal Type
High viscosity pump is a volumetric internal engagement gear pump, the active gear (external rotor) drive the passive gear (internal rotor) rotation, constantly produce closed space, in the oil absorption area gear gradually out of engagement and liquid constantly filled with teeth and was brought to the oil area, gear in the oil area into engagement when the liquid is discharged.
The combined action of the two rotating gears forms a stable volume displacement without pulsation.
Since the pump is completely symmetrical, the pump can be reversed and the direction of the flow changes accordingly.
However, it should be noted that the steering of the pump may be limited by the seal or other structures in the pump.
